Mr Broad told ABC radio on Wednesday after the results came out that he would now vote for same-sex marriage in parliament.

“A large number of Australians participated in the postal survey regarding changes to the Marriage Act. There will be some Australians who are pleased with the result and some who will be displeased,” Mr Broad said.

“I have been impressed by the decent manner in which the people of the Wimmera, Mallee and Mildura have conducted themselves.

“The result gives direction to the Australian Parliament.”

It will now require the wisdom of Members of Parliament to work through the legislation to ensure there is balance between honouring the result and ensuring freedoms are available and maintained.”

Ms Ostapiw said she was very happy that Mr Broad would now vote in favour of same-sex marriage, saying he was “very honourable” to have kept his promise.
